a dividing curtain: Heb. פָּרֹכֶת. [This is] a word denoting a dividing curtain. In the language of the Sages [it is called] פַּרְגוֹד (Chag. 15a), something that separates between the king and the people.

four pillars: inserted into four sockets, with hooks attached to them [the pillars], bent on the top [in order] to place upon them a pole around which the top of the dividing curtain was wound. These hooks are the וָוִין [mentioned in the next verse, given this name] because they are made in the shape of [the letter] “vav” (ו). The dividing curtain was ten cubits long, corresponding to the width of the Mishkan [from north to south], and ten cubits wide, like the height of the planks. [It was] spread out at the one-third [point] of the Mishkan [from east to west], so that from it [the dividing curtain] toward the [Mishkan’s] interior were ten cubits, and from it [the dividing curtain] toward the exterior were twenty cubits. Hence, the Holy of Holies was ten [cubits] by ten [cubits], as it is said: “And you shall place the dividing curtain beneath the clasps” (verse 33), which join the two sets of the curtains of the Mishkan, the width of the set being twenty cubits. When he [Moses] spread them on the roof the Mishkan from the entrance [all the way] to the west, it [the first set of curtains] ended after two-thirds of the [way into the] Mishkan. The second set covered [the remaining] third of the Mishkan with the remainder [of the curtains] hanging over its rear to cover the planks.

33"And you shall place the dividing curtain beneath the clasps. You shall bring there on the inner side of the dividing curtain the Ark of the Testimony, and the dividing curtain shall separate for you between the Holy and the Holy of Holies.

And you shall place the table: The table was in the north, drawn away from the northern wall [of the Mishkan by] two and one-half cubits. The menorah was [placed] in the south, drawn away from the southern wall [by] two and one-half cubits. The golden altar was placed opposite the space between the table and the menorah, drawn a short distance toward the east. They [the table, menorah, and golden altar] were all situated in the inner half of the Mishkan. How was this? The length of the Mishkan from the entrance to the dividing curtain was twenty cubits. The altar, the table, and the menorah were drawn away from the entrance toward the western side ten cubits. — [from Yoma 33b]

And you shall make a screen: Heb. מָסָ, a curtain that is a protector opposite the entrance, like “You made a hedge (שַׂכְךְתָּ) around him” (Job 1:10), an expression of protection. [Note that the “samech” and the “sin” are interchangeable.]

the work of an embroiderer: The figures [on the screen] are produced on it with needlework-just as the face [was] on one side, so was the face on that [other] side. — [from Yoma 72b, Baraitha Melecheth HaMishkan, ch. 4]

an embroiderer: Heb. רֹקֵם, the name of the craftsman, not the name of the craft. Its Aramaic translation is עוֹבַד צַיָיר, work of an artist, but not עוֹבֵד צִיוּר, work of artistry. The measurements of the screen were the same as the measurements of the dividing curtain, [namely] ten cubits by ten cubits. — [from Baraitha Melecheth HaMishkan, ch. 4]
